Detailed explanation-1: -Concerns that animal biotechnology might narrow the gene pool and reduce genetic diversity, so producing monocultures which could be vulnerable to new diseases or other environmental threats. Concerns that organs from genetically modified animals might transmit viral diseases if used in human transplant surgery.
Detailed explanation-2: -For example, human insulin, a small protein used to treat diabetes, is made in genetically engineered bacteria, whereas large, more complex proteins like hormones or antibodies are made in mammalian cells or transgenic animals. Antibiotics and vaccines are products of microorganisms that are used to treat disease.
Detailed explanation-3: -This presentation summarises their core ethical arguments. Five sets of ethical concerns have been raised about GM crops: potential harm to human health; potential damage to the environment; negative impact on traditional farming practice; excessive corporate dominance; and the ‘unnaturalness’ of the technology.
